  • Latter part of last week was a bit of a disaster having to make two trips to London to see the immigration lawyer
  • Got the vessel into the building! YAY, everyone knows what happened... it was an adventure.
  • CLEANING! lots and lots of cleaning, the vessel was extremely dirty on the inside (and outside)
Added:
>
>
    • Two soap washes
    • Two water washes
    • 1 Alcohol wipe
 
  • Put curtains back on clean tent (required cleaning also)
  • re-plummbed the hydrolic lines on the vessel, had to tighten a few other fitting
  • Made inventory list of parts we recieved from Cryovac
  • Notes
    • All gas regulators have TIPOC inlet fittings, we will have to change this for relivent DIN/CGA fittings for use in the lab
Changed:
<
<
    • Captured o-ring kf fittings are good for 10bar, note, we appear to have no spares!
    • Vacuum valve... if that is rated to 5 bar id be surprised. Looks like some random valve they found somewhere in the bushes. Part number is SA0150MVQF, technically rated between atmosphere and Vacuum

    • Vacuum valve... if that is rated to 5 bar id be surprised. Looks like some random valve they found somewhere in the bushes. Lesker Part number is SA0150MVQF, technically rated between atmosphere and Vacuum. Internal construction is probably capable of holding back 5 bar, but... yeah... dodgy.
 
    • Chamber has 3 missing caps - they are plastic caps that have been taped on. All are KF40s, I think these were the ones used to pressure test with the HV feedthroughs.
Changed:

    • We will probably want to put a steel brush pipe cleaner through the water drain and air release valves (top and bottom penetrations on the vessel) Both show corrossion and are generally hard to clean.

  • Lots of meetings with Sam / Cryovac, good news is that the vessel should 'should' be here today, keep fingers crossed.
